'We can confirm that the object is not a cockroach, but a fly. On initial inspection we believe that the fly has not been baked, and it most likely entered the loaf post production, rather than on our site.

'We will be able to confirm this after further testing.’

A spokesperson for Costcutter said: 'Quality is a priority for Costcutter Supermarkets Group and all of its retailers, particularly when it comes to products.

'It is unfortunate that this particular loaf of Kingsmill bread was purchased in one of our stores.

'We hope Kingsmill will swiftly deal with the situation to Mr Backon's satisfaction and ensure it does not happen again.'
